Good question. You think it would be easy like the KBT SH HUD you have shown, but who knows. It seems modding anything that is "hardwired" into the default Hornet is very hard to change. Think bout the workarounds weve had to go thru to get the "new HUD" or the brute force workaround for full-deflected flaps (45 trailing edge) at the correct landing airspeeds.
Good luck in your quest. BTW, looking at your HUD pic, do you use TrackIR? Just wondering as your HUD seems non-conformal to the actual horizon in that pic. Also, IF you do indeed use TrackIR, what are your results with it? Do you like it?
